Application November 13, 1951, Serial No. 256,059 7' Claims. (01. 210-165) This invention relates to filters for use in filtering fluids of various types and kinds. More particularly, the invention deals with a device of this kind employing a filter unit, or assemblage, which is readily detachable with respect to the casing of the device and, particularly, wherein floating or freely movable tubes are disposed within the filter coils, so as to encourage vibratory or other movement of the tubes facilitating filtering operation.

Still more particularly, the invention deals with a device of the character described, having valve control means at the lower portion thereof for draining condensation and foreign particles from respective chambers of the device.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. 1 is a longitudinal sectional view through a filter device made according to my invention, diagrammatically illustrating the filter coils and tube mountings.

Fig. 2 is an enlarged broken section of one of the tubes and part of a coil arranged thereon, clearly illustrating clearances provided for circulation of filtered fluid through the device.

Fig. 3 is an enlarged plan view of the structure, as seen in Fig. 1, with parts of the construction broken away.

Fig. 4 is a section on the line =r 4 of Fig. l, with part of the construction broken away.

In Fig. l of the drawing, I have shown, at IS, the tubular casing, or cylinder, of the filter device or apparatus, the casing having a downwardly inclined bottom wall H, having a large opening l2 therein. The upper portion of the casing has an outwardly extending flange [3, upon which a coupling ring I4 is adapted to bear, the ring being generally of the peripheral contour or a closure plate or head !5, note Fig. 3, and a plurality of bolts It are employed at corner portions of the head 55 and ring 4 for clamping the head onto the casing Ill, the flange 53 seating upon a ring gasket I? in the head, as clearly seen in Fig. l of the drawing.

Centrally of the head 15 is a tubular portion it which extends into the casing I i! and mounted thereon is a coil or gas resistant rubber ring 19 which is self-sealing against the pressures which may prevail.

At one side of the head [5 is an admission port 26, into which the fluid, such as oil, gas or the like is adapted to pass from a source of supply, not shown, under a predetermined pressure. At 2| is shown a vertical port for placing the port 26 in communication with the chamber 22 of the casing.

At the opposed side of the head 15 is an exhaust port 23, which communicates with the bore 24 of the tubular portion It for discharge of filtered fluid to a suitable receiving station, not shown, in the manner more specifically described hereafter.

At the lower portion of the casing l0 and fitting in the aperture 12 is a tubular bearing member or sleeve 25. This member has a reduced upward extension 26, on which is mounted a sealing ring 21, similar to the ring 9. The bore 28 of the member 25 is threaded to receive a valve body 29 which seats on a sealing ring or gasket 36 on the bottom wall H of the casing. This construction secures and positions the member 25 centrally of the bottom of the casing, as will be apparent.

Mounted transversely of the valve body 29 is a tapered valve 3|, having diverging ports 32 for placing the discharge 33 of the body 29 in communication with ports 34 opening intoan annular chamber 35 in said body.

The member 25, adjacent the bottom wall ll of the casing, has circumferentially spaced recesses 35, which place the lower drain or sediment chamber 31 of the casing in communication with the annular chamber 35.

The valve 3! has a port 38 which is adapted to register with a bore 39 in the body 29 opening into the bore 28 to drain a chamber 49 formed in the lower portion of a filter unit 4| The filter 4| comprises two heads '22, 42' which are of similar or identical construction, the head 42 being disposed at the lower portion of the filter in the construction shown, but this head might assume the upper position of Fig. 1. Each head comprises a casing part 43, 43' having a hub portion 44, 44 to engage the sealing rings 21, H9, respectively, and a plate portion 45, 45'. The plate portion 45 and the casing part 43 forms the chamber 40, whereas 43', 45 form a corresponding chamber 48', with which the bore 24 communicates for the discharge of filtered fluid through the port '23.

In view of the reduced dimensions of the sh0W- ing in Fig. 1, Fig. 2 has been illustrated to show, on an enlarged scale, the mounting of the filter coils and tubes in connection with the heads 42, 42'. The plate 45, 45"of each head ha a plurality of radially and circumferentially spaced ports, or passages, 65, 66, in enlarged portions of which are mounted flanged cups .or bushings 41, l? forming seats for end portions of sprin like filter coils it, or filter elements of any type or kind which are of tubular construction. Characteristics of the filter coils will depend largely upon the type of fluid being filtered and, while coils of the type and kind shown: in Fig; 6 of my prior- Patent Number 2,458,118'oi- January. 4, 1949, may be employed, I have indicated in Fig. 2, at 48, coils having circumferentially spaced pro jections, as at 49, controlling the filter passages between the Coi s in accordance with the tea'ch ings in my application, Serial Number 1133,5535, filed September '7, 1950.

Disposed within each of the -filter'coils 41lE is a tube 58, preferably of a non-corrosive material,

and this tube is of less. outside diameter than the interior of the coil ifiand also of the passages tion of Fig. 2. In this case, it'ls to be kept in mind'that the clearances herein referred to are not attempted to be shown in Fig; 1 and, for this reason, Fig. 2 has beenprovided" to clearly show the passagesb, 55, aswell as the cham' her 5"! between each tube 5% and'the coildS. It will, thus, be seen that fluid introduced intothe chamber 22, note Fig; 1,,mustfirst passthrough the coils 58, thus into the chamber 5i andthen into the chambers lit, ill at theheads 62, 42 and this filtered fluid is free to pass'through'the tubes 59 into the chamber as for discharge through the ports 26, 23.

In this connection, it will be noted that the walls of the casings d3, 43 aretapered or sloping so that clearance is provided betweerrthe lower ends of the tubes 5t and the taperedwalls of the casing 43. The same'result' would be accomplished if the unit were mounted in the filter in the reverse direction.

It will appear from a consideration of-Fig. 1 of the. drawing that the parts 43, 45'; A3, 45 are secured together by screws or other fastenings, asat 52,52? and a center bolt andspacing mem-' ber 53 is employed for coupling the heads 42, 42 in predetermined.spacedrelationship to each other, thus keeping the'unit assemblage between the heads 5-2, 42'.

It will be. understood that the tubes'Efi have a free vertical as well as lateral movement within the coils 455, thus these tubes are subjected to sideways vibratory movement in. pressure injection of fluid to be filteredthrough the coilsonto the tubes and are also free to move vertically'in the unit, as will be apparent;

InF-ig. l of the drawing, the"valve.3l is shown in its opened position in order. to clearly illustrat the port arrangement. Eowever, by operating the fingerpiece orhandleli l of the valve, the same can be moved into closed position to seal the discharge 33 whenflthe filterdevice, or

apparatus, is in operation. It will also be apparent that the upper end of the port or bore'fl is sealed by a plug 5 3,

In the use of the filter, it will be understood that gasoline, oil or other fluid can be introduced into the chamber 22 through theports 2n; 2! and pass through the multiplicity of filters 43" employed and, then, into the chambers 5! and through the ports 65, 46 andxtubes 56 finally into'the chamber-ill and, then, out through the ports 23, 24. In this operation sediment is adapted to be collected in the chamber 37; as well as water or the like'and water may also 'be" 4 collected in the chamber to or the chamber 28 and passage 39, so that, from time to time, and, particularly, when the filter operation is at rest, foreign particles, water and the like may be discharged through the discharge 33 by moving the valve 3| into open position.

My improved device, or apparatus, lends itself for cleaning or repair by quick detachment of the head: I 5. which. facilitates removal-of the unit M. from. the casing l9: Itwill also be. understood that, in some instances, it will be possible toiprovide a reverse circulation of fluid through the device or apparatus by admission of fiuid through the port 23 and discharge of sediment or .the like, including fluid through the port 20,

although, in some instances, such, for example, asztherfiltrationzof gasoline, this is not necessary by. virtue of the drainage provided for water'or'condensation and foreign particles, here keeping in mind that vibratory movement of the tubes, including the filter elements will encourage deposit or the solids or foreign particles in the chamber 31 for intermittent discharge by movement ofthe valve 35 into open position.

The rings ll, 19- and 2?" can becomposed of ployed. In-this connection, the bushings ll, 51'

' can also be made of such material so as to effect a seal of the filter elements 58 in the plates l5, 45'.
